The Mariners' move to get Buhner, an All-Star and Golden Glove winner, is considered one of the best trades in Seattle’s history -- and one of the worst for the Yankees during some dark days in New York. Phelps first caught the eye of the Yankees when he hit 14 home runs in half a season with the M’s in 1988. However, after being traded to the Yankees, he couldn’t keep his hot streak going and saw a major drop in production. Meanwhile in Seattle, Buhner hit 307 home runs and had 951 RBIs in 14 seasons. In 1991, he had the first of seven consecutive 20-homer seasons. From 1995-1997, Buhner had three straight 40 home run seasons. Evers never made it to the big leagues.

In one of the biggest trades in Mariners history, Johnson was shipped to the M’s by the Montreal Expos (now the Washington Nationals). In his 10 years with Seattle, the Big Unit won 130 games with a 3.42 ERA, 2,162 strikeouts and 19 shutouts in 1,838.1 innings pitched. While Johnson played for Seattle, the hard-throwing lefty went to five All-Star games won the 1995 Cy Young Award. Johnson will be inducted into the National Baseball Hall of Fame on Sunday.

December 10, 1993:
Mariners send P Mike Hampton and OF Mike Felder to the Houston Astros for RF Eric Anthony.

Hampton was drafted by the M’s in the sixth round of the 1990 MLB Draft, but after getting the call to the major leagues in 1993, the Mariners gave Hampton only 17.0 innings before shipping him off to Houston. By 1995, Hampton was an everyday starter in Houston. He won 69 games with a 3.40 ERA in the six seasons after being traded, finishing second in the National League Cy Young voting in 1999. For his career, Hampton was a two-time MLB All-Star, winning five Silver Slugger Awards and a Gold Glove. He was the MVP of the 2000 NL Championship Series and pitched in the 2000 World Series with the Mets. Meanwhile, Anthony became a reserve outfielder and didn’t contribute much to Seattle.

After winning his first Gold Glove award in 1993 with Seattle, Vizquel was traded away to the Indians where he won eight more Gold Gloves from 1994 to 2001. He is one of baseball's all-time best fielding shortstops. In return, the M’s got Fermin, who was a regular starter during the 1995 season and led the AL in sacrifice hits in 1989. Jefferson played one year with Seattle before being granted free agency and signing with the Boston Red Sox.

August 15, 1995:Mariners send P Jim Converse to the Kansas City Royals for LF Vince Coleman.

As Seattle's left fielder during the 1995 season, Coleman was a spark plug during the playoff push. One of the few mid-season rentals in Mariners history, Coleman hit .290 in the regular season before slumping to .163 with a lone RBI in the postseason. Coleman signed with the Cincinnati Reds the following offseason. Converse got hurt in 1996 when playing for the Royals, causing him to miss the entire year. When he came back in 1997, he pitched just 5.0 innings.

After being drafted by Seattle No. 14 overall in 1988 and spending six seasons with the M’s, Martinez -- a fan-favorite -- was traded away to the Yankees at the end of the 1995 season. Just prior to the trade, Martinez had a breakout year, driving in 111 runs with 31 home runs and a .293 average. In the Big Apple, Martinez helped lead New York four World Series Championships in seven years. Davis hit 66 homers for Seattle in four seasons. In 1996, Hitchcock went 13-9 with a 5.35 ERA in his only season with the M’s.

In one of the best Mariners trades to date, they acquired the winningest pitcher in franchise history in 1996 when they gave up seldom-used outfielder Darren Bragg for Moyer. Before he won over 145 games over 11 seasons in Seattle, Moyer went 7-1 in 23 appearances for the Red Sox. The ageless Moyer had a 3.97 ERA win 11 seasons with Seattle and was selected to his only All-Star game in 2003 at age 40. Moyer will be inducted into the Mariners Hall of Fame on Aug. 8.

September 13, 1996:
Mariners send 1B David Ortiz to Minnesota Twins for 3B Dave Hollins to complete an earlier deal made on August 29, 1996.

"Big Papi" began his professional career with the M’s, signed as an amateur free agent in 1992 before working his way through the M's minor league system. Ortiz never got a chance to play in the big leagues with Seattle after he was traded to the Twins in 1996. While Ortiz wasn't a star in Minnesota, he went on to become a nine-time All-Star in Boston, leading the Red Sox to two World Series titles while hitting 482 career home runs (and counting). Hollins hit .351 in 94 at-bats before signing with the Anaheim Angels the following offseason.

At the time, this trade seemed like a good idea for the M’s. They viewed Slocumb, who had a 5.79 ERA and blew 5 saves in 22 opportunities in Boston, as someone who could bolster the back end of the bullpen for their supposed upcoming playoff run. Giving up Lowe and Varitek didn’t seem like a big deal. However, Slocumb got hit hard during his 96 innings in Seattle before he was traded away the following season. Lowe and Varitek, meanwhile, combined to make five All-Star teams and won the 2004 World Series together in Boston.

Entering the final months of his contract with Seattle, Johnson wanted a massive extension to stay with the M's. But after they fell out of contention, Johnson was traded -- minutes before the deadline -- to Houston for three up-and-coming prospects. Johnson went 10-1 with a 1.28 ERA with Houston to help lead the Astros to the playoffs before signing with Arizona the next offseason, where he would win four-straight Cy Young Awards and a World Series in 2001. The trio of Garcia, Guillen and Halama were key players in Seattle's 116-win season in 2001.

After Griffey demanded a trade in November of 1999, the Mariners were stuck in a difficult position. Many teams were interested in the rising star, who only had one year left on his contract, and the M’s were losing leverage. Seattle ended up trading Griffey to the Reds -- one of the four teams Griffey wanted to be traded to –- so he seemed to get what he wanted after all. Griffey never led the Reds to the playoffs and found himself on the DL more times than not in Cincinnati. For Seattle, Cameron was a bright spot for Seattle, averaging 22 home runs and 152 games played, while winning a pair of Gold Gloves, in his four seasons with the M's.

One of the worst trades in team history; expected ace Bedard made a total of 46 starts in a Seattle uniform from 2008 to 2011 and missed all of 2010 due to a shoulder injury. He had a 15-14 record with a 3.31 ERA before being traded to the Red Sox. To make matters worse, the Mariners gave up Jones, a four-time all-star and Gold Glove winner. Tillman was an All-Star in 2013, and went 13-6 last season with 3.34 ERA.

Cliff Lee was brought to Seattle in the 2010 offseason to pair with Felix Hernandez to give Seattle one of the best 1-2 punches in baseball. But, while Lee did very well in Seattle -- posting a 2.34 ERA and a 89-6 strikeout-to-walk ratio -- the lowly Mariners failed to win and were forced to trade Lee just three short months after acquiring him. The Lee trade was mostly centered around obtaining Smoak, who at the time was considered one of the best-hitting prospects in baseball. Smoak hit a measly .226 in five seasons with the M’s before being selected off waivers by the Toronto Blue Jays in October 2014.

January 14, 2012:
Mariners send P Michael Pineda and P Jose Campos to the New York Yankees for P Hector Noesi and C Jesus Montero.

Montero was expected to be a star for the Mariners to build around, but he's ended up being a huge disappointment -- at least thus far. After a promising rookie year in 2012, when he hit .260 with 15 home runs and 62 RBIs, he showed up to spring training the following season out of shape and ended the season batting .208 with 3 home runs in 29 games before being sent to the minors. Noesi spent only 2 years with Seattle before being traded in April 2014, posting a 6.13 ERA and a 2-14 record in his 36 appearances with the M’s. Pineda has only pitched in 31 games in New York, sporting a 3.01 ERA.
